A Heating Ventilation and Air Conditioning System (HVAC) surge protection system works similarly to a surge protector for computers. You will find that if an electrical surge occurs, your surge protector will shut down the system so that your HVAC unit does not get damaged. An HVAC surge protection system will protect you, your family, and your HVAC system.
Another form of HVAC surge protection will be for a malfunctioning HVAC unit. If something goes wrong, the system will shut down. This is a safety measure for your HVAC system. You will need to contact a technician to find out why the HVAC surge protection unit is being triggered if you are not sure why this is happening and it is happening often.
